I also think the church is by far the most effective of the bunch. The composition is perfectly balanced among all the elements. It has a nice graphic impact, bordering on the surreal. I don't often like photos of country churches, but this works nicely for me.

I think the second barn picture is better than the first, there seems a little more mid-grey in the planks and I expect decaying wood to be softer edged.To me the upper door make the barn seem deeper (front to back) than the lower one, possibly because the lower entrance has a bright background, so I don't know if you can darken that slightly to give a sense of depth and make the planks stand out more? (I'm useless at PP so it might look unnatural).

Does anyone else see what appears to be a halo on the left roofline of the church building? I cannot decide if it's a processing artifact or a bizarrely fortuitous arrangement of white cloud.

Good catch. It's there. It could be a jpeg compression artifact, especially if it's an out-of-camera jpeg. But it could also be baked into the RAW file, in which case it would be much harder to get rid of.

Chris - I'm going to have to go against the flow on this one. I guess I'll never grow up to be a PHOTOGRAPHER. I strongly prefer the second version of the barn to the church. To me, the tonality of the church is a bit harsh and the near perfect symmetry leaves the image with no depth. To be touchy-feely, the church is 'in your face' and leaves you no room to explore, the graphic elements too sparse to be entertaining. I'll freely admit that my comments reflect totally my preferred style and not much more. Without being dryly academic, it is hard to critique without reflecting one's preferences. That is quite apparent in many of the critiques I've read here.

I like your theme concept and look forward to seeing more. Choose your own style, whatever that is.
